Bioactive proteins and peptides isolated from Chinese medicines with pharmaceutical potential. [PDF]

open access: yes, 2014
Some protein pharmaceuticals from Chinese medicine have been developed to treat cardiovascular diseases, genetic diseases, and cancer. Bioactive proteins with various pharmacological properties have been successfully isolated from animals such as Hirudo ...

Computational design of fusion proteins against ErbB2-amplified tumors inspired by ricin toxin

open access: yesFrontiers in Molecular Biosciences, 2023
Although the anti-cancer activity of ricin is well-known, its non-specific targeting challenges the development of ricin-derived medicines. In the present study, novel potential ribosome-inactivating fusion proteins (RIPs) were computationally engineered

Ribosome‐inactivating proteins up to date

open access: yesFEBS Letters, 1986
Ribosome‐inactivating proteins (RIPs) from plants inactivate eukaryotic ribosomes, as far as studied by rendering their 60 S subunit unable to bind elongation factor 2. These proteins seem widely distributed and possibly ubiquitous in plants. They are either type 1, those consisting of a single polypeptide chain, or type 2 (ricin and related toxins ...

Preparation of an antitumor and antivirus agent: chemical modification of α-MMC and MAP30 from Momordica Charantia L. with covalent conjugation of polyethyelene glycol [PDF]

open access: yes, 2012
Background: Alpha-momorcharin (α-MMC) and momordica anti-HIV protein (MAP30) derived from Momordica charantia L. have been confirmed to possess antitumor and antivirus activities due to their RNA-N-glycosidase activity. However, strong immunogenicity and

Functional Assays for Measuring the Catalytic Activity of Ribosome Inactivating Proteins

open access: yesToxins, 2018
Ribosome-inactivating proteins (RIPs) are potent toxins that inactivate ribosomes by catalytically removing a specific adenine from the α-sarcin/ricin loop (SRL) of the large rRNA.

Toxicity of the Anti-ribosomal Lectin Ebulin f in Lungs and Intestines in Elderly Mice

open access: yesToxins, 2015
All parts of dwarf elder (Sambucus ebulus L.) studied so far contain a ribosome-inactivating protein with lectin activity (ribosome-inactivating lectin; RIL), known as ebulin. Green fruits contain ebulin f, the toxicity of which has been studied in six-

Dianthin and Its Potential in Targeted Tumor Therapies [PDF]

open access: yes, 2019
Dianthin enzymes belong to ribosome-inactivating proteins (RIPs) of type 1, i.e., they only consist of a catalytic domain and do not have a cell binding moiety.

Impairing the production of ribosomal RNA activates mammalian target of rapamycin complex 1 signalling and downstream translation factors [PDF]

open access: yes, 2014
Ribosome biogenesis is a key process for maintaining protein synthetic capacity in dividing or growing cells, and requires coordinated production of ribosomal proteins and ribosomal RNA (rRNA), including the processing of the latter.

Novel Ribosome-inactivating Protein (RIP) Isolated from Trichosanthes dioica Induces Apoptosis in HeLa Cell Line

open access: yesInternational Journal of Bio-Resource and Stress Management, 2021
Ribosome-inactivating proteins (RIPs) are toxic N-glycosidases that depurinate eukaryotic and prokaryotic rRNAs and thus interrupt protein synthesis during translation.

Ricin trafficking in plant and mammalian cells [PDF]

open access: yes, 2011
Ricin is a heterodimeric plant protein that is potently toxic to mammalian and many other eukaryotic cells. It is synthesized and stored in the endosperm cells of maturing Ricinus communis seeds (castor beans).
